Poetry environment breaks when Homebrew upgrades Python on MacOS

まず、推奨されているインストールスクリプトと Homebrew による Python のアップグレードを使って失敗を再現し、次に、インストール済みの Poetry 環境が Python フレームワークをどのように参照しているかを調べます。アップグレード後に poetry --version で結果を確認し、Poetry をアンインストールして再インストールしなくても引き続き使用できることを確認します。

Issue experienced in Poetry 1.2.1
Python version 3.10.6_2 -> 3.10.7 and 3.10.7 -> 3.10.8 upgrades
OS version MacOS 12.6
(not project-specific so no pyproject.toml)

Issue

Poetry commands cease working and throw errors after upgrading the installed Python version using Homebrew. This has occurred the last two times (3.10.6_2 upgrade to 3.10.7 and 3.10.7 upgrade to 3.10.8) using brew upgrade which included the two Python updates. Afterward, attempting to use any Poetry command fails with error output similar to the following:

poetry --version
dyld[42062]: Library not loaded: '/usr/local/Cellar/python@3.10/3.10.7/Frameworks/Python.framework/Versions/3.10/Python'
  Referenced from: '/Users/keith/Library/Application Support/pypoetry/venv/bin/python'
  Reason: tried: '/usr/local/Cellar/python@3.10/3.10.7/Frameworks/Python.framework/Versions/3.10/Python' (no such file), '/Library/Frameworks/Python.framework/Versions/3.10/Python' (no such file), '/System/Library/Frameworks/Python.framework/Versions/3.10/Python' (no such file)
zsh: abort      poetry --version

In both cases, the only Python installations available are system packages (if these even still exist) or those installed by Homebrew. Poetry has only been installed via the recommended curl -sSL https://install.python-poetry.org | python3 - command. The only way I've found to restore Poetry functionality after brew upgrade is to uninstall via the same recommended script i.e. curl -sSL https://install.python-poetry.org | python3 - --uninstall and then to reinstall Poetry
